HANGING LAMP.

SPECIFICATION forming part of Letters Patent No. 290,341, dated December18, 1883. Application filed May 10, 1883. (No model.)

To all whom it puny concern-.-

Be it known that LVILLIAM S. McLEwEE, of New York, in the county andState of New York, have invented a certainnew and useful Improvement inHanging Lamps, of which the following isa specification.

The object of my improvement is to provide for raising and loweringahanging lamp, and also to enable the reservoir and its appurtenances tobe drawn down, so as to separate it from its shade or the draft-inducingdevices to facilitate lighting the burner.

The improvement consists in the combina tion,with alamp-reservoir and ashade or draftinducing device, of cords, bands, or chains connected atone end with the reservoir or a holder, in which it is supported, and atthe other end with the shade or draft'inducing device, pulleys overwhich these cords, bands, or chains pass, other cords, bands, or chainsconnected at one end with the said pulleys and at the other end to aweight, whereby the entire lamp is counterbalanced, and a hangerprovided with pulleys over which the last saidthe hanger.

Similar letters of reference designate corresponding parts in all thefigures.

A designates a reservoir for oil or other illuminating material. As hereshown, it is provided with a burner, B, which maybe of any of thewell-known kinds for burning kerosene.

G designates a holder, which may be made of metal, and which receivesand supports the reservoir A.

D designates a globe, shade, or shield, which may be made of glass, andat the top has an outwardly-projecting lip, S, fitting within a metalring or crown, E, as shown in Fig. 2. This ring or crown is vdetachablysecured in place by screws a, passing through the ring or crown andextending under the lip S.

Rods F extend from the holder 0 up into the globe, shade, or shield D;and G designates cords, bands, or chains, which at one end are fastenedto these rods, and, extending thence over pulleys H, are at the otherend fastened to the ring or crown E. The pulleys H are supported inframes or straps b. To these frames or straps b are attached cords,bands, or chains Lwhich extend over pulleys J in a hanger, K, and haveattached to their depending ends a weight, L, of sufficient heft tocounterbalance the lamp.

The entire lamp may be adjusted into different positions by lifting itor pulling it down as a whole, as the counterbalance-weight willmaintain it in any position to which it may be adjusted. To prevent theconsumption of the oil or preponderance of the weight of the portions ofthe cords, bands, or chains I on either side of the pulleys J fromaffecting the poise of the lamp, I may make the pulleys J turn withconsiderable friction, yet not too much to prevent the lamp from beingadjusted by hand to different positions. I may for this purpose adoptthe construction shown in Fig. 3. As there shown, the pulley J is keyedor otherwise secured fast to its shaft or axle J, and the latter has atone. end a head, 0, and at the other end nuts (1 d screwed upon it. Theshafts or axles rotate in bearings 6, formed in the hanger K, and bymeans of their nuts cl (1 the pulley shafts or axles may be clamped intheir bearings, so that their rotation will be more or less resisted orretarded by friction.

The globe, shade, or shield D and its ring or crown E are heavier thanthe lamp-reservoir and its appurtenances; hence they will more thancounterbalance the reservoir and its appurtenances, and the globe,shade, or shield will normally rest on the reservoir or on anappurtenance thereof.

When the burner is to be lighted, the reservoir is pulled down, so as toseparate it and the globe, shade, or shield.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

In a lamp, the combination,with a reservoir and a shade ordraft-inducing device, of cords, bands, or chains connected at one endwith the reservoir or a holder in which it is supported, and at theother end with the shade the last said cords, bands, or chains pass,subor draft-inducing device, pulleys over which I stant izrlly asspecified. these cords, bands, or chains pass, other cords,

- q a 7 y bands 0r chains connected at one end with the Muir TD 5 saidpulleys and at the other end to a weight, \Vilnesses:

whereby the entire lamp is counterbalanced, T. J. KEANE, andahangerprovided with pulleys, over which J AMES R. BOWEN.
